my dr. gave me some antibiotics friday that i've been taking ever since and i called him today to tell him i had strept throat and he called me in another antibiotic and he told me to take both but i never took to different antibiotics at the same time and i was wondering if it was safe to do so? the antibiotics are generic ceftin 500mg andgeneric zithromax 250mg and i also have a sinus infection which is why he gave me ceftin.i also have a script for generic liquibid-d tabs 600mg/40mg and i have a bad headache and want to take some ibuprofren.is it ok to take all these meds together?
